Moved from Minnesota to Delaware Mid-Year: Which State Tax Returns Do You File?
Answer
Both states want a return, but neither taxes the whole year. Moving from Minnesota to Delaware splits the tax year at the date your residency changed: a Minnesota part-year return covers everything before it, a Delaware part-year return everything after. Income is assigned by when it was received.

Part-year returns are designed so that neither state taxes the whole year. The risk is not double taxation by default; it is misassigning income received near the move date, and losing the proration on deductions and credits.

Questions people actually ask
I moved from Minnesota to Delaware mid-year. Do I have to file in both states?
Both states want a return, but neither taxes the whole year. Moving from Minnesota to Delaware splits the tax year at the date your residency changed: a Minnesota part-year return covers everything before it, a Delaware part-year return everything after. Income is assigned by when it was received.
How do I split my income between Minnesota and Delaware?
By when you received it, measured against the date your domicile actually changed. Income received while you were a Minnesota resident belongs on the Minnesota return and income received afterwards on the Delaware return, with each state prorating your deductions, exemptions and credits to its own part of the year. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
